Introduction: i need help please help me

More Details: An ionic crystal Sodium Chloride of a three dimensional lattice of alternating positive Na+ and negative Cl-. Calculate the dissociation energy needed to separate the

crystal completely into ions. Compare this with the experimentally measured value -7.93 eV and comment on the result. (Distance between the Na+ and Cl- ions is 2.82

Angstrom). Note that you have to use the potential energy between ions. You also need to find the potential energy per unit cell. You can check undergraduate solid

state physics texts.
